[Icecast] Configure Ubuntu Server 16.04 for icecast2

Those speed tests are best case scenario - one big old file where the only overhead would be tcp syn/acks.

5000 x syn/acks and handshakes everytime a client connects would quite a lot of overhead I imagine.

Note that this is an educated guess - I don't run /anything/ on the scale of 5000 users lol
